The project

PhoneSat is a nanosatellite, categorizing the mass as between one
and ten kilograms. Additionally, PhoneSat is a 1U CubeSat, having a
volume of around one liter. The PhoneSat Project strives to
decrease the cost of satellites while not sacrificing performance.
In an effort to achieve this goal, the project is based around
Commercial Off-The-Shelf (COTS) electronics to provide functionality
for as many parts as possible while still creating a reliable
satellite. Two copies of PhoneSat 1.0 are being launched mid April
2013 along with an early prototype of PhoneSat 2.0 referred to as
PhoneSat 2.0.beta. PhoneSat 2.4 is sitting on the launchpad ready for lift-off.

Amateur radio operators

PhoneSat satellites are emitting packets on the amateur radio
spectrum to report different types of message. The details of these
packets can be found on the packets
page. If you are an amateur radio operator and you can receive
these packets, you have the great opportunity to contribute to the
project by submitting them. The dashboard
page will give you all the information you need to track the
satellites in real time.
